Are needle biopsy harmful

Needle biopsy is usually not harmful. The needle is hollow, with a gap in the middle and an inclined tip. It usually does not cause bleeding during the puncture process. Ultrasound or CT is usually used to guide the puncture, which can ensure the accurate puncture site. In the process of puncture, bleeding is more likely to occur. Because the puncture needle is relatively thin, mainly including models of 0.9mm, 1.22mm and 1.6mm, it can cause less damage and generally will not lead to massive bleeding.

A 1.22mm puncture needle is usually selected for puncture under the guidance of ultrasound or CT. There will be a certain amount of pathological tissue removed from the gap of the needle, and the pathological examination will be carried out on it. The pathological examination result is benign or malignant, and the final treatment plan will be decided.
